Unfortunately. The WWE needs to get new champs before they lose a good portion of their audience who are getting sick of the same people.
Khali won because the WWE is trying to push that he has basically taken the Big Shows place as the giant in the WWE and if you look at the list of these giants such as Andre The Giant , Yokozuna and Big Show you see that all had big title reigns so I reckon Khali might hold that title a little longer then expected.
Khali will hold his title just long enough to say he held the World Title probably till either Summerslam or Unforgiven and then lose it again. The WWE can't put him as their champ because he has no real experience and he is not exactly the best face to represent the company well.
